Yeah, go to bluelight.nu (the psychedelics forum) and do a search for 2c-i and "liquid measure" about a million posts related to this, I skimmed through them and saw no problems with 2c-i in water, but I won't claim to have read them all. I've personally seen 2c-i dissolved in vodka (half water), without problems.The best theory on 4ho stuff turning black is that it is oxidation, which is removed metabolically, thus not affecting potency. Iodine is a dead end as far as any kind of chemical reaction, so I can't imagine the same thing happening with 2c-i.
